Loading a String from a embed tag containing no variable names

Hi, I’m develloping a little image loading application for a client.
the same swf has to be reused over and over to load the files.
They are passing me the image location in the embed tag but they are not using the usual

flash.swf?path=folderpath&img1=image1.jpg&img2=image2.jpg&img3=image3.jpg

instead they are using this format :

flash.swf?/folderpath/::SPLIT::image1.jpg::SPLIT::image2.jpg::SPLIT::image3.jpg
do you know how I can read those variables into my flash file ?

any help would be greatly appreciated.

Thank you.
